| New progress in poplar comparative genomics research |
Recently, the team of Professor Wan Xueqin from the College of Forestry of Sichuan Agricultural University published an online publication on BMC Genomics, a full-genome study and expression profile analysis of the polyphenol oxidase (PPO) gene family, revealing the organ development and stress of Populus tomentosa The potential function of the reaction" research paper
.
Poplar is the most widely distributed and adaptable tree species in the world
.
Mainly distributed in northern hemisphere temperate and cold temperate forest tree species, 22°~70° north latitude, from low altitude to 4800 meters
In this study, a genome-wide analysis of the poplar PPO family was performed, and 18 PtrPPO genes were identified
.
Then use bioinformatics and qRT-PCR technology to analyze the gene structure, phylogeny, chromosome location, gene duplication, cis-elements and expression pattern of PtrPPO
The research and analysis will help to select candidate genes for subsequent biological function research, understand the molecular genetic basis of forest tree stress resistance, and will also help the development of forest tree genetic resources
